Citing “vicious comments,” the group working to repeal Ohio’s gay marriage ban canceled a meeting with established groups Human Rights Campaign (HRC) and Equality Ohio.

Earlier this month, Ohio’s Ballot Board cleared a proposed amendment filed by Freedom to Marry Ohio which would legalize gay marriage in the state. It would repeal a constitutional amendment defining marriage as a heterosexual union, which passed in 2004 with overwhelming support.

The group now must collect roughly 385,000 valid signatures from at least half of Ohio’s 88 counties to get the proposal on next year’s ballot.
